This report covers the possibility of using the optical excitation of surface plasmons by Attenuated Total Reflection ATR for the investigation of the metal-electrolyte interface. The method is very sensitive to the modifications of the interface, and it allows studies which are otherwise extremely difficult to perform using classical optical techniques. By the ATR technique, the author investigated the modifications of the complex wave vector of the surface plasmons, and these have a clear physical meaning. This technique was used in performing potentiometric and optical studies of Au-electrolyte interfaces both polarization at the interface between gold and H2SO4 and HClO4 solutions, and also the anodic oxidation of gold in H2SO4 were investigated.
